Here's a very interesting article which points out how research results come into conflict with real life earthquake situations. It's a good read...Petra

"SACRAMENTO -- The San Fernando Valley likely will not suffer earthquakes stronger than those that were centered in Sylmar in 1971 or Northridge in 1994, according to a new research report published in the journal Geology.
Using advanced measurements of magnetic fields on sediments and other information, seismic researchers at Oregon State University found that the earth's crust in the Valley and the Santa Clarita Valley to the north is broken up into blocks rather than being in a single piece as it is in the San Gabriel Valley and areas of eastern Ventura County."
